hi, I want to migrate away from Solaris with ZFS to Linux with XFS (BTRFS is to young) . At the moment, I have Solaris 10 with ISCSI initiator running and a zpool with a size round about ~17TB. The ISCSI target is a Linux Debian with "tgt" Daemon and connected via SAS (LSI Logic / Symbios Logic SAS2008) to several LSI JBODS (630j). Every jbod has 12 (2TB) disks and managed by mdadm as a RAID6 device and on top LVM. I have two ISCSI target servers (one for _cold_ standby) and all servers has power connection via UPS and a second direct one. As I sad, I want to get away from Solaris 10 and know I search for options to use XFS with save options, in case of emergency (poweroff etc.). We use the JBODS mostly for backups (bacula) so, performance/realtime isn't imported, since network is the limit. Under ZFS I can make sure, with zpool scrub (file system check), that all data are completely written and consistence. But what is the best way under XFS? Should I remount XFS every month for a file system check (re/mount) ? What happens in the case, of ISCSI problems? So, I need just a few suggestions :-) cu denny
